The TE5000 is amazing. Great flavor and it stays charged for a long time. The BC5000 Ultra- Watermelon Ice is another favorite of mine, unfortunately it is going away. ELFBAR is an amazing product, the flavors are amazing, and the battery stays charged a long time. BIG D Vape is the best store to get any product, the staff is amazing and very knowledgeable. I wouldn't go anywhere else but Big D's. I don't write a lot of reviews, but this place is better than ANY other place in the Metroplex. Give them a try, you will be thanking me. Superb experience!
